Surprising, but welcome news from my doc

This is the culprit. Why I can't stay awake past 10 pm, but can't stay asleep past 3:30 a.m. Why I have no appetite. Why my hairbrush had decidedly too much hair stuck on it lately. Why I have this anxious feeling in my gut ALL THE TIME. Why I wake up sweaty almost every night. Even why my periods have nearly disappeared.

This tiny blue pill that I have no choice but to take every single day for the rest of my life has turned my life upside down. Those of you who blamed my symptoms on IF - and you know who you are - guess what? You were right .... kind of.

So, what is this little blue pill, you ask? Synthroid.

The Back Story

On Good Friday, 1999, I was given the cheery news that I had Papillary Carcinoma of the thyroid gland.
For those of you who are unfamiliar with this butterfly-shaped organ, the thyroid gland is a small gland, normally weighing less than one ounce, located in the front of the neck. It is made up of two halves, called lobes, that lie along the windpipe (trachea) and are joined together by a narrow band of thyroid tissue, known as the isthmus.

The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4. T3 and T4 are then released into the blood stream and are transported throughout the body where they control metabolism (conversion of oxygen and calories to energy). Every cell in the body depends upon thyroid hormones for regulation of their metabolism.

Since my thryoid gland was clearly not going to be doing me any favors, they removed it. And, since as noted above in bright red bold type, thyroid hormones are kind of important, I have to take a man-made version.

Enter SYNTHROID® a synthetic T4 replacement that is identical to the hormone produced in the human thyroid gland (pictured top).

I've been taking the same dose - a suppressive dose of 150 mcg - since the surgery in 1999. They amped up the dosage to ensure there is no further thryoid tissue activity of any kind anywhere in my body to prevent any recurrence of the cancer if any cells escaped the great excavation of my neck.

Anyway, in 12 years, even though I gained a few pounds here and lost a few there, my labs were always nearly identical - until today.

Compared to my last blood tests done in July of 2010, my TSH (thyroid stimulating hormone) has been beaten beyond the point of submission and my T4 levels have traveled to a land never before seen in my body and are well above the high of the normal range.

Comparisons of my blood tests in July 2010 and Feb 2010 - with the only difference in my life being my intermittant fasting program (and the ensuing 12-lb weight loss) - here is where I stand:

TSH: Then: less than 0.068 / Now: less than 0.006

(Thyroid Stimulating Hormone is what they want to keep quite low, but not this low)

Antithyroglobulin AB: Then:92 / Now: 96 - slightly elevated today

T4, Free (Direct): Then: 1.69 / Now: 2.12 - quite elevated today

Basically, what these numbers mean is that I'm now hyperthyroid. Hence the symptoms outlined above. So, to correct the situation and prevent worsening symptoms such as heart palpitations and bone loss, the doctor has lowered my dose to 137 mcg for two months and said he may have to lower it again depending on my test results at that time.

What I find the most interesting is that it would seem, as illustrated clearly in my labs, that my IF lifestyle has made my body more sensitive to the Synthroid, thus increasing the uptake. Therefore, I now need less medication to achieve the desired result of a suppressed TSH.

And less of any kind of medication can't be a bad thing.

Stay tuned and I'll let you know in a week or two if my insomnia and other symptoms are improving.

Optimal Fasting Times for Female Fat Loss - A discussion.

How long should I fast? This is probably the most common question I see among women new to Intermittent Fasting. Unfortunately there is no hard-and-fast definitive answer to this question. We all react to stress differently. Yes, I said stress. Fasting is a stressor to the body - especially the female body. Like money worries, relationship drama, and exercise, fasting will cause the body various levels of stress which can, and often will, result in negative consequences regarding our health. I'm going out on a limb here, but I'm guessing most of you have jobs and financial responsibilities, relationships, some of you have children or are care takers of family members. You probably rarely get eight hours of sleep and, let's face it, who has time to meditate daily when living in the real world? All of these things are life's stressors. Now, add lack of sleep, job and family/relationship stress to a boiling pot of intense daily e...

Finally - Progress Pics

Recently I've been struggling with my motivation. I felt like I wasn't getting anywhere. My workouts stalled (poor diet, lack of discipline and no sleep). Then, today, I hopped on the scale to a solid 116.0 lbs (was literally 117.8 yesterday at the same time). I think the two pints of Guinness I had to celebrate St. Patty's with my girlfriend and the bar appetizers I shouldn't have eaten may have given me the "Whoosh" that Martin Berkhan speaks of. "By the way, a nice bonus after a night of drinking is that it effectively rids you of water retention. You may experience the "whoosh" effect, which I've talked about in my two-part series about water retention. That in itself can be motivating for folks who've been experiencing a plateau in their weight loss." In any event, I'm pleased at my results so far and look forward to seeing how I will look in another two months - just in time for Memorial Day at the Jersey Shore. Here the...

Saying Bye Bye to my Fat Clothes...

Here is just a sampling of what I am sure will be a towering pile of fat clothes I will never again need in my life. Pictured here: 2 pair of jeans 1 pair cropped khakis 2 pair khaki sorts 1 pair camo cargo shorts 1 T-shirt 1 Columbia undershirt 1 pair gray slacks If you want to know why they're in the donation pile, check out the photos below. I've never been so happy to do spring cleaning. Only problem is I'm pretty thin on clothes that fit and I don't want to buy much yet as I'm nowhere near as lean as I'm hoping to get...ah, the trials and tribulations of Leangains . Damn you, Martin! :) ...
